FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

CashAddr codec for Bitcoin Cash in pure PHP — BCH polymod checksum, base32 payload, network prefixes and token-aware CashTokens address types as a typed immutable value object.
A CashAddr encoder / decoder for Bitcoin Cash written in plain PHP, with no runtime dependencies and no extensions. It implements the CashAddr specification — the 40-bit BCH polymod checksum over GF(2^5), the base32 alphabet, the version byte with its size bits — and the two token-aware address types added by CashTokens. Parsed addresses become a final readonly CashAddress value object that always prints in the normalized prefix:lowercase form, so two spellings of one address compare equal.
Features
- Spec-exact codec —
CashAddr::encode()/decode()handle every hash size the spec defines (160…512 bits) and any prefix;CashAddr::isChecksumValid()checks the polymod alone. - Typed address —
CashAddresscarries aCashAddrNetwork(bitcoincash,bchtest,bchreg), aCashAddrTypeand the raw hash. - Token-aware types as an enum —
P2PKH(q),P2SH(p),TokenAwareP2PKH(z),TokenAwareP2SH(r);isTokenAware()lets a caller refuse token addresses where it cannot handle them,plain()/tokenAware()convert between the pairs. - Prefix optional —
qr6m7j9n…is matched against the known networks by checksum, or against the one you pass. - Strict input — upper case is accepted, mixed case is rejected, a double prefix is rejected, padding bits must be zero, the version byte must match the payload length.
- Hash sizes per address type — 20 bytes for P2PKH, 20 or 32 bytes (P2SH32) for P2SH.
Installation
Usage
The lower layer works with any prefix and any spec hash size:
Test vectors
The suite runs every vector of the CashAddr specification (checksum vectors, legacy translation table, 160…512-bit payloads) and the CashTokens cashaddr.json set with the token-aware types, in both directions and in upper case.
Requirements
- PHP 8.3+ on a 64-bit build (the polymod state is 40 bits wide)
